A loft conversion is the most cost-effective way to add a proper bedroom, en-suite or home office to a West London house without losing a foot of garden. Convert Extend handles dormer, mansard, hip-to-gable and gable-end conversions, with the drawings, the party-wall side and the build all run under one roof.
Scope scales with the project, but these areas are the spine of any loft conversions job with Convert Extend.
The two workhorses of the West London loft. A rear dormer gives you full standing height and a flat roof for the new floor; a mansard rebuilds the roof line and suits Victorian terraces under permitted development or planning.
For semis and end-of-terrace houses, squaring off the hipped roof into a gable wins a surprising amount of usable space. Often combined with a rear dormer for a full-width loft room.
New steels, floor joists and a staircase that lands sensibly without eating the landing below. We plan the stair early because it is what makes a loft feel like part of the house rather than a bolt-on.
Fire doors, insulation, escape windows and the building control inspections that get the room signed off as habitable, with the completion certificate handed over at the end.
Many rear dormer lofts go ahead under permitted development, but conservation areas, mansards and anything affecting the front roof slope usually need a full application. We assess yours at the first visit and handle whichever route applies.
A typical dormer loft on a West London terrace runs 8 to 10 weeks on site. Mansards and hip-to-gable conversions with more structural work tend to run 10 to 14 weeks. You get a programme with dates before we start.
Yes, almost always. Most of the work happens up top and is reached through scaffolding, so the disruption inside is limited to the week the new staircase goes in. We seal the work area off and keep the house liveable throughout.
We check the ridge height at the survey. As a rule, if you have around 2.2m from the existing ceiling joists to the ridge, a conversion works. Where it is tight, a mansard or a raised ridge can solve it, and we will tell you straight if it does not stack up.
Yes. Loft work on a terrace or semi almost always triggers the Party Wall Act with the neighbours either side. We deal with the notices and surveyors as part of the job so it does not land on you.
Based in Ealing with a second base in Buckinghamshire, we cover West London and the surrounding area as a matter of course.
A quick chat with Steve is usually enough to tell whether your loft conversions is straightforward or needs a proper look. No detail is too small to start with.
